ObjectiveTo explore the correlation between open field test(OFT) and light-dark box (LDB),as two animal models of state anxiety in Kunming mice.MethodsThe behavior of adult,male,Kunming mice in OFT and LDB was recorded by sequence,for five minutes,with a one-week inter-trial interval.The following parameters were evaluated:percentage of time exploring in the OFT central area( OFT-Ctime％ ) ; percentage of squares crossing in the OFT central area( OFT-Ccross％ ) ; total number of squares crossing in OFT(OFT-Cross) ;total number of rears in the OFT(OFT-Rear) ; number of fecal boli in OFT(OFT-FB) ; percentage of time exploring in the LDB light area( LDB-Ltime％ ) ; percentage of squares crossing in the LDB light area( LDB-Lcross％ ) ;and percentage of rears in the LDB light area( LDB-Lrear％ ) ; transitions between two areas in LDB( LDB-Transition) ; total number of squares crossing in LDB(LDB-Croas) ; total number of rears in LDB(LDB-Rear) ; number of fecal boli in LDB (LDB-FB).Subsequently,factor analysis,cluster analysis and correlation analysis were calculated for these parameters.ResultsFactor analysis and cluster analysis of variances from either OFT or LDB revealed a three behavioral dimensions:anxiety factor ( loaded by OFT-Ctime％,OFT-Ccross％ or LDB-Ltime％,LDB-Lcross％,LDB-Lrear％ ),activity factor ( loaded by OFT-Cross,OFT-Rear or LDB-Transition,LDB-Cross,LDB-Rear) and emotionality factor(loaded by OFT-FB or LDB-FB).While all the variances from both OFT and LDB in combination were analyzed,it could be seen as five components:' LDB-anxiety factor ( loaded by LDBLtime％,LDB-Lcross％ and LDB-Lrear％ ),' OFT-anxiety factor ( loaded by OFT-Ctime％ and OFT-Ccross％ ),'LDB-activity factor (loaded by LDB-Transition,LDB-Cross and LDB-Rear),'OFT-LDB-emotionality factor( loaded by OFT-FB and LDB-FB) and 'OFT-activity factor (loaded by OFT-Cross and OFT-Rear).Good correlation were found between OFT/LDB factors alone and in combination,such as OFT-emotionality factor and LDB-emotionality factor(Pearson =0.383,P＜0.05),LDB-anxiety factor and 'LDB-anxiety factor( Pearson =0.989,P＜0.01 ),OFT-anxiety factor and 'OFT-anxiety factor( Pearson =0.934,P ＜ 0.01 ),LDB-activity factor and 'LDB-activity factor ( Pearson =0.956,P ＜ 0.01 ),OFT/LDB-emotionality factor and ' OFT-LDB-emotionality factor ( Pearson =0.835,P＜0.01 ;Pearson =0.696,P＜0.01 ),OFT-activity factor and 'OFF-activity factor( Pearson =0.926,P＜0.01 ).ConclusionEither OFT or LDB comprised three behavioral dimensions:anxiety factor,activity factor and emotionality factor; however,it was difficult to establish face validity as a point-to-point concordance between OFT and LDB.Attention should be paid to heterogeneity of animal models when OFT and LDB were in combination as a behavionomics to evaluate anxiolytics in Kunming mice.

Objective To summarize the pattern and main characteristics of fatal cases related to medical disputes in Yancheng area. Methods Sixty fatal cases of medical disputes were retrospectively analyzed to elucidate the annual incidence, characters of distribution of hospitals, gender and age of the decedents, types of diseases, and cause of death. Results Among 60 fatal cases, most cases happened in health clinics of county, township and village. There were more males than females. The major medical specialties in-volved included internal medicine, surgery, gynecology and pediatrics, with the internal medicine specialty having the highest incidence. Conclusion Police institutions have advantages in investigation of these cas-es in their jurisdictions, which could enhance the ability of local medicolegal examination.

Objective To summarize the subtle anatomical structures of the normal nasal bone in mul-ti-slice spiral CT (MSCT) image through the observation of the three-dimensional images. Methods One hundred and twenty volunteers who had no nasal trauma and disease history were collected. The nasal was scanned using MSCT. Raw data was reconstructed into bone window images (slice thickness 0.6 mm, slice interval 0.5 mm), and then the images were imported into Syngo Imaging XS software to recon-struct three-dimensional images and to summarize the nasal bone ’s subtle anatomical structures. Results The subtle anatomy of normal nasal bone generally included four seams, two holes and one edge. The four seams were left and right nasal-maxillary suture, nasal-frontal seam, and internasal suture. The two holes were left and right nasal aperture. The edge of the nasal was the lower edge of the nasal bone. In addition, there was suture bone in internasal suture in some normal nose. The nasal aperture mostly was hole-like, but some nasal apertures were line shape. The nasal edge can be divided into flat type, wave-shaped type, inverted spike type, hook-shaped type and others. Conclusion The anatomy diversity and individual differences in nasal bone are large. MSCT and three-dimensional image reconstruction techniques, combined with the history of trauma could distinguish between the normal anatomy and fractures.

This article was aimed to study the factors associated with sleep quality of anger-out and anger-in population based on the frequent pattern-tree (FP-Tree) growing algorithm with data mining. The algorithm of structuring frequent model FP-tree and mining frequent itemsets were designed. The database information scanned was recorded by using FP-Tree growing algorithm through state-trees. The frequent itemsets met minimum support required was generated through reducing the search space of project sets and scanning database only one. The data mining of all factors associated with emotional diseases was actualized. The results showed that factors associated with sleep quality of anger-out and anger-in population were disturbance in respiration, cough or snoring, feeling cold, hot or nightmares. The total time for program analysis was 2 seconds. It was concluded that data mining algorithm based on FP-Tree frequent itemsets can effectively realize the useful information receiving from factors associated with emotional diseases.

Editor's Notes: The basic theory of traditional Chinese medicine is the theoretical foundation of Chinese medicine , modernization of Chinese medicine needs of the modern theory of Chinese medicine urgently . However , it is always the important issues about how modern Chinese medicine theory should be created , and what kind of theory should have been established concerned and explored by domestic and foreign counterparts in tradi-tional Chinese medicine . To lead the development of modern Chinese medicine theory , Modern Basic Theory of Traditional Chinese Medicine series of symposiums are set up specially in the current Review column, and discussed thoroughly and systematically using three consecutive pats respectively. Among them, part I contains 3 articles about new concepts, new theories, new disciplines; part II contains 5 articles about new ideas, new norms, how to clear concept, how to verify hypotheses, why to evaluate theory; part III contains 12 articles about concept of wholism updating, treatment based on syndrome differentiation development, viscera-state doc-trine innovation, pathogeny, etiology, pathogenesis, prevention, principle of treatment, knowledge structure, cogni-tion structure , monographic study , 5-year outlook . Published article on this issue is the first one belong to new concept of part I. In this paper, we want to describe the denotation and connotation of the new concept of the modern basic theory of traditional Chinese medicine from three aspects of a concept: a label , a theoretical definition , and an operational definition learning from the international academic understanding of scientific concepts, demonstrate the necessity of theoretical premise to the research and establishment of the modern basic theory of traditional Chinese medicine and the need to build on , illustrate the inevitable trend toward modern science . The whole article contains profound meaning and a certain breakthrough and innovation. We are expected to cause concerns and discusses of experts and scholars through this article .

This paper was aimed to analyze the theoretical connotation with liver bodyyin with function yang, and to explain the physiological and pathological mechanism of body yin and function yang, respectively. The mechanism of its corresponding syndrome and symptoms were described and the composing principle of classical prescription for liver regulation was analyzed. The clinical significance of liver body yin with function yangwas confirmed by clinical cases. This paper argued that the liver ascending characteristics, which is a necessary guarantee for ascendingqi in the human body to adapt to the ascending gas of the world, is the key point to maintain balance of qi ascending and descending in the body. The liver ascending disorder mainly manifested for the excessive ascending and ascending deficiency, which analyzed the pathogenesis characteristic and clinical manifestation of the liver qi ascending disorder. This paper put forward a new view that the liver storing blood referred to the convergence and the conservation properties of the liver, which demonstrated the relationship between liver storing blood and controlling dispersion. It suggested that liver blood convergences liverqi so as not to make liverqi too excessive. The liver storing blood can raise spirit. Liver blood is the source of menstruation, and etc. This paper finally put forward the clinical prescription viewpoint of soothing liver and dropping inverse should raiseyin and gentle liver necessarily, releasing liver should raise liver and nourish blood and clearing away the liver-fire should cool blood and nourishyin. This research had certain clinical value.

Objective To explore the behavioral dimensions of the open field test ( OFF),as a method for ethology in Kunming mice.Methods The behavior of adult,male,Kunming mice in OFF was recorded twice,for five minutes,with a one-week inter-trial interval.The following parameters were evaluated by factor analysis:percentage of time exploring in the central area (Ctime％); percentage of squares crossing in the central area (Ccross％) ; total number of squares crossing in the whole apparatus(Cross) ; total number of rears in the whole apparatus(Rear) ; and number of fecal boli(FB).Results There were good intercorrelation and intracorrelation between test and retest for Ctime％,Ccross％,Cross and Rear.Ctime％ and Ccross％ had significant loadings on “Anxiety” factor ( Loading％:43.34％,48.56％ ) ; Cross and Rear loaded on “locomotor-Exploration” factor ( Loading％:27.94％,29.30％ ) ; and FB loaded on “Emotionality” factor ( Loading％:21.95％,15.93％ ).A good correlation was found between test and retest for anxiety factor and locomtor-exploration factor.Conclusion Open field test,as a method for ethology in Kunming mice,comprise three behavioral dimensions:anxiety factor,OFF-activity factor(locomotor-exploration) and emotionality factor.

Objective:To investigate the application value of three-dimensional visualization technology in management of middle hepatic vein (MHV) processing in associating liver partition and portal vein ligation for staged hepatectomy(ALPPS).Methods:The retrospective and descriptive study was conducted. The clinical data of 40 patients with right massive liver cancer or multiple right liver lesions who underwent ALPPS in the First Affiliated Hospital of Guangxi Medical University from November 2017 to August 2019 were collected. There were 34 males and 6 females, aged (44±9)years, with a range from 26 to 64 years. All patients underwent multi-slice computed tomography (CT) plain and enhanced scan of superior abdominal region before operation, and the data were transmitted to the liver visualization analysis software IQQA system with 1.5 mm thin-layer images to complete the three-dimensional reconstruction of the liver and its blood vessels. Patients were performed ALPPS based on results of three-dimensional reconstruction and intraoperative findings. Observation indicators: (1) results of preoperative three-dimensional reconstruction; (2) surgical situations; (3) follow-up. Follow-up was conducted using outpatient examinations and telephone interview to detect postopeartive survival of patients up to March 2020. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were described as M (range). Count data were represented as absolute numbers. Results:(1) Results of preoperative three-dimensional reconstruction: 40 patients underwent three-dimensional reconstruction successfully, of which 37 clearly showed MHV, tumor location and relationship between them, 3 patients showed unclearly MHV and were classified based on two-dimensional images. Of the 40 patients, 12 had MHV classified as type A, 13 as type B, 9 as type C, and 6 as type D. Three-dimensional reconstruction of vessels showed 22 with umbilical veins and 9 with anterior veins. Of the 40 patients, 35 were predicted to preserve MHV, and 5 were predicted to resect MHV. Total estimated liver volume, tumor volume, and reserved liver volume were (1 012±119)cm 3, 600 cm 3(8-2 055 cm 3), (346±80)cm 3. The ratio of future liver remnant to standard liver volume was 34%±8%. (2) Surgical situations : 40 patients underwent the first-stage ALPPS, including 35 with preservation of MHV and 5 with resection of MHV, which was accorded with preoperative prediction. Thirty-four patients underwent the second-stage ALPPS, and 6 patients had failure to receive the second-stage ALPPS due to undificiency future liver remnant. The operation time and volume of intraoperative blood loss for 40 patients undergoing first-stage ALPPS were (350±79)minutes and 300 mL(range, 100-2 600 mL). Three patients received blood transfusion and no perioperative death occurred. There were 24 patients with grade A heptic insufficiency according to criteria of International StudyGroup of Liver Surgery (ISGLS) and 16 patients with grade B heptic insufficiency after the first-stage ALPPS. Twenty-eight patients had grade Ⅰ complications of Clavien-Dindo classification, including 17 with a small pleural effusion, 10 with a small pleural and abdominal effusion, 1 with hypoproteinemia; 8 patients had grade Ⅱ complications of Clavien-Dindo classification, including 5 with pneumonia, 1 with pneumonia combined with pleural and abdominal effusion, 1 with coagulation disorders, 1 with biliary fistula; 3 patients had grade Ⅲ complications of Clavien-Dindo classification, including 2 with pneumothorax and pneumonia, 1 with pneumothorax, pneumonia and coagulation disorders; 1 patient had grade Ⅳ complications of Clavien-Dindo classification as systemic inflammatory response syndrome. All patients with complications were improved after symptomatic treatment, anti infection, transfusion of fresh frozen plasma or drainage. For the 34 patients undergoing the second-stage ALPPS, the operation time and volume of intraoperative blood loss were (320±83)minutes and 500 mL(range, 200-6 000 mL). Twelve patients received blood transfusion. There were 12 patients with grade A heptic insufficiency according to criteria of ISGLS and 22 with grade B heptic insufficiency after the second-stage ALPPS. Eighteen patients had grade Ⅰ complications of Clavien-Dindo classification, including 11 with a small pleural effusion, 7 with a small pleural and abdominal effusion; 12 patients had grade Ⅱ complications of Clavien-Dindo classification, including 4 with pneumonia, 4 with coagulation disorders, 3 with massive abdominal effusion, 1 with biliary fistula; 3 patients had grade Ⅲ complications of Clavien-Dindo classification, including 1 with pneumothorax and pneumonia, 1 with massive pleural effusion, 1 with obstructive jaundice; 1 patient had grade Ⅳ complications of Clavien-Dindo classification as pneumonia and anemia. All patients with complications were improved after symptomatic treatment, anti infection, transfusion of fresh frozen plasma or drainage. (3) Follow-up: 40 patients were followed up for 2-35 months, with a median follow-up time of 17 months. The 6-month, 1-, and 2-year survival cases were 35, 26, 21 cases. Conclusion:Three-dimensional visualization technology can clearly show the MHV classification and its relationship with tumor location, which has an important guiding significance in the decision-making of MHV management in ALPPS.
